ABSTRACT
Among 207 914 multimember households with a tinea case, a secondary case was diagnosed in another household member in 8.5%. Excluding same-day diagnoses (20%), the median time from index case to first secondary case was 138 days. To prevent household tinea transmission, appropriate treatment and strategies to reduce environmental contamination are needed.

Introduction: Onychomycosis is common among adults with diabetes mellitus (DM). We used two-sample Mendelian randomization to estimate the causal effect of genetic risk for DM on onychomycosis and tinea skin infections in the All of Us Research Program. Methods: Onychomycosis and tinea corporis, pedis, manus, and cruris cases were identified using electronic health record data, and genetic instrument variables and summary statistics were collected from a type II DM (T2DM) genome-wide association study (GWAS) meta-analysis. Results: Inverse variance weighted regression showed positive effect of T2DM genetic risk on onychomycosis (beta = 0.135, p = 1.86E-2), and weighted median regression produced a comparable estimate of effect size (beta = 0.148). There was no significant effect of T2DM on skin dermatophytosis. Conclusions: Our results suggest that T2DM has a positive causal effect on onychomycosis but not tinea skin infection risk. As onychomycosis may impair occupational function and increase risk for secondary soft tissue infections, patients with diabetes should be screened for onychomycosis and counseled on mitigating infection risk.
ABSTRACT
Background: As self-applied manicures have gained popularity, it is important for physicians to remain informed about potential associated side effects. Traditional polish remains most popular among nail enthusiasts, but the pursuit of durability and convenience accelerated development of other nail cosmetic products, including gel polish, acrylic nails, and press-on nails. Despite documented adverse effects among beauty professionals and salon customers, individuals practicing at-home nail care routines may face similar, if not more, frequent complications due to misinformation, inadequate training, and social media trends. Summary: This review provides an overview of adverse effects associated with different at-home nail cosmetics. Allergic contact dermatitis is the most prevalent adverse event, primarily attributed to (meth)acrylates found in nail glue, gel polish, and acrylic nails. Other adverse effects include infections, chemical burns, and complications from ultraviolet nail lamps. Key Message: The review highlights the importance of transparent product labeling and appropriate warning labels from manufacturers, as well as physician education and awareness for minimizing risks related to at-home nail cosmetic applications.
ABSTRACT
Introduction: FOXP1 syndrome is a rare neurodevelopmental disorder due to forkhead box protein 1 (FOXP1) gene mutations and is associated with intellectual disability, dysmorphic features, and autism spectrum disorder. We aimed to assess body-focused repetitive behavior (BFRB) prevalence in this patient population using a cross-sectional survey-based study. Methods: A validated survey assessing for BFRBs was administered to parents attending the International FOXP1 Foundation conference on June 21, 2023, and was sent to a FOXP1 syndrome listserv. Results: Excoriation disorder, onychophagia, onychotillomania, and trichotillomania were reported by 58.6%, 38.6%, 29.7%, and 10.0% of subjects, with 63.4%, 59.3%, 54.5%, and 14.3% having moderate to severe disease, respectively. Overall, 28.6%, 30.0%, and 10.0% had one, two, and three BFRBs, respectively. Conclusion: Prevalence of BFRBs is high among FOXP1 syndrome patients surveyed, affecting quality of life for patients and their families and causing significant sequelae.
ABSTRACT
In this part 1 of a 2-part continuing medical education series, the epidemiology, clinical features, and diagnostic methods for fungal skin neglected tropical diseases (NTDs), which include eumycetoma, chromoblastomycosis, paracoccidioidomycosis, sporotrichosis, emergomycosis, talaromycosis, and lobomycosis, are reviewed. These infections, several of which are officially designated as NTDs by the World Health Organization (WHO), cause substantial morbidity and stigma worldwide and are receiving increased attention due to the potential for climate change-related geographic expansion. Domestic incidence may be increasing in the setting of global travel and immunosuppression. United States dermatologists may play a central role in early detection and initiation of appropriate treatment, leading to decreased morbidity and mortality.
ABSTRACT
In this part 2 of a 2-part continuing medical education series, the management, outcomes, and morbidities for fungal skin neglected tropical diseases (NTDs), including eumycetoma, chromoblastomycosis, paracoccidioidomycosis, sporotrichosis, emergomycosis, talaromycosis, and lobomycosis are reviewed. While fungal skin NTDs are associated with poverty in resource-limited settings, they are more often associated with immunosuppression and global migration in the United States. These infections have a high morbidity burden, including disfigurement, physical disability, coinfection, malignant transformation, mental health issues, and financial impact. For most fungal skin NTDs, management is difficult and associated with low cure rates. Dermatologists play a central role in initiating appropriate treatment early in disease course in order to improve patient outcomes.
